Fomepizole alone for severe infant ethylene glycol poisoning.

Objective: To report a case of a massive ingestion of ethylene glycol in an infant successfully treated by fomepizole without hemodialysis.

Design: Descriptive case report.

Setting: Pediatric intensive care unit.

Patient: A 5-mo-old boy who ingested 200 mL of an antifreeze solution.

Interventions: Antidotal therapy with a total of seven doses of fomepizole administered intravenously with an interval of 12 hrs (15 mg/kg as loading dose, then 10 mg/kg). Hemodialysis was not performed.

Measurements And Main Results: Iterative determination of ethylene glycol concentration was obtained in blood and urine. Kinetics were calculated for ethylene glycol and fomepizole elimination. The infant made a complete recovery with no change in renal function.

Conclusions: Although not yet approved for this indication in the child, fomepizole seemed safe and effective in a case of severe ethylene glycol poisoning, without the need for hemodialysis.
